How it is calculated
How to convert hectares to acres
acres = hectares × 2.4711 and hectares = acres × 0.4047. A hectare is a square of 100 × 100 m, 10,000 m². An acre is 43,560 square feet, which with the international foot is exactly 4,046.8564224 m², or 0.40468564224 ha. One hectare therefore holds 1 ÷ 0.40468564224 = 2.4711 acres.

Picturing the areas
A soccer field of 105 × 68 m covers 0.714 ha, which is 1.7643 acres. An acre is a little smaller than an American football field without the end zones. A square kilometer is 100 ha or 247.1054 acres, and a square mile, 640 acres, is 258.9988 ha. Rule of thumb: hectares × 2.5 gives acres within about 1 %.
Survey acre and international acre
Older US land records used the survey foot, which made the acre about 4,046.873 m² – a difference of 4 parts per million, invisible at farm scale. Since 2023 the US uses the international foot for surveying, so the acre here is 4,046.8564224 m². For smaller plots switch to acres to square feet or square meters to acres.
